Z '0 all whom it may concern:

lle it known that I, il -rennet A. (hero, a zen of the United States, "residing at aliln'aulcee. in the county of Milwaukee and Tjtate of lVisconsin, have invented. new and useful Improvements in Wheel-Trucks and Brake-Gearing, of which the following is a specification.

This invention relates to improvements in wheel trucks and brake get ring for railway cars particularly freight cars, and one of its objects to provide a truck structure by means of which the brake beams may be mounted directly thereon, in such a main nor to dispense with the ordinary brake hangers and obviate any liability of the brake beains becoming disconnected and dropping A seem object is to provide a truck and brake srear construction which adniits of the arrangement of the brakes in such a manner as to furnish adequate room for the movements of the brare beams, as well as for the op ration of thehand brake gearing to secure proper leverage.

A stilll'urtl r o iect ot the invention .is to provide a ruck structure whereby the above stated advantages may be secured, and

whereby eachside plate oi a truck frame may be formed of a single casting with tended end portions to carry the outside brake beams beyond the wheels.

A still ".l urther olject of "the invention is to provide a truclr and brake gear structure whereby in the event of the wearing away of the brake shoes and brake heads grinning away of: the ends ofthe brake beain will be avoided. thus preventing liability of dropping of the o 3111 while permitting all the other brake beams of a car to becperated in the usual manner.

A still "further object of the invention is to, provide a construction whereby a. brake beam and brake heads may be moved inteoral in a single cisting. i A still further object of the invention is to provide simple and eliective guiding means whereby an inside brake beain may be mounted for efli ient action upon the truck.

With these and other objects in view the invention cons' of the features ofcorn struetion, conil'nnation and arrangement of Specification of Letters latent.

Fl is a similar view on an enlarged scale showing the construction at one end of the truck. Fig. 4 is a fragmentary perspective view of a brake beam. Fig. 5 is a top plan view of a wheel track showing a construction for inside brake beams. 'Fig. 6 is a vertical longitudinal section. on line (36 of Fig. 7 is a perspective view of one of the guide brack ets. Fig. 8 a vertical transverse section of the same. Fig. 9 is a fragn'ientary perspective view of one of the inside brake beams. Fig. 10 is a fragmentary side elevation showing a modified construction. 11 is a cross section on the line 1.1-4.1 of Fig. 10.

Referring to Figs. 1 to l, inclusive of the drawings, 1 designates the side plates of a truck frame, 2 the journal boxes at the ends thereof 3 the wheel axles, "l the wheels n'i'ounted thereon, the spring supported truck bolster, and 6 the sand board. lhe bolster and its supporting ineansinay be of any of the constructions in common use, and the side plates of the frame may be con.- nected and tied in any preferred manner, also the general construction and arrangement of parts may vary under different con ditions of service and to suit dillerent types of cars. Each side plate 1 is'eoinposed of a steel casting. and comprises, as usual, a substantially diamond-shaped body 7 formed with the guide opening .8 to receive the adjacent end of the bolster 'The journal boxes 2 are arranged in the ordinary manner at the reduced ends of the side plates, but, in accordance with my, invention. 1

also provide the extensions 9 with longitudh nally disposed strengthening ribs,- webs flanges 11. The plate 1, body portions of ment of the beams is provided with beams against cndwise movement and with abutment or stop surfaces '21 to engage the the journal boxes, and the end extensions 9 are preferably formed of a single steel castmg, thus securing strength and durability with economy of construction. It will, of course, be understood that any suitable type of cross-ties or connections between the side plates may be employed.

12 designates the outside brake beams, and 13 the extended reduced ends thereof. Each 01 these beams is formed of a steel casting provided with brake heads 14 cast integrally therewith, the beam being suitably constructed to receive the brake lever bracket 15, and the brake heads being suitably constructed to receive the brake shoes 16. The extensions 9 of the side plates 1 are provided at theii outer ends with longitudinally extending angular guide slots 17, which receive guide members 18 on the ex-. tended ends 13 of the beams 12, whereby said beams are mounted to slide towardand from thewheels in the application and retraction of the brake shoes. The slots'17" open through the outer ends of the extensions 9, to permit the beams to be readily applied and removed, and casual displaceprevented byretaining pins 19 headed at one end and apertured at the opposite end to receive cotter pins 20, whereby they are held in position. It is evi.- dent that with this construction the outside brake beams may be mounted beyond the wheels and directly upon the truck frame, thus allowing the beams to have an ample range of motion, while at the same time dispensing with the use of hangers and the necessity of mounting the beams upon the car body. The beams are therefore securely sustained in position and cannot therefore become displaced or disconnected, thus obviating liability of accidents from the beams becoming detached and dropping. The inner ends of the slots 17 terminate slightly beyond the tread surfaces of the wheels, and .the end partitions 13 of the beams are stop shoulders 21 to hold the inner end walls of the slots, whereby, in the event. thatil-ie brake shoes are worn away the brake heads and ends of the beams will be prevented from coming in contact with the wheels and ground oil", thus obviating any liability of the beams becoming displaced and dropping down.

In accordance with my invention, as shown in Figs; 5 to 9. inclusive, illustrating a construction for the useof inside brake beams, the inside brake beams 22 are slidably mounted within the slotted end portions 2 of a longitudinally extending guide bracket 24. suitably secured to 'the sand board 6. and said bracket is preferably composed of two longitudinally divisible sections 25 and 26 united by'bolts or other Suitable fastening inner brake beams, which are carried directly upon the truck frame, an ample range .of 1nove1nent,of said beams ispermitted, and as these beams are arranged in direct horizontal alinement with beams a maximum efficiency of braking acthe outer brake tion is secured. This mode of mountingalso increases the range of motion so that proper leverage of the hand brake mechanism for -adgusting said brake beams 1s afi'orded. As

irithe structures shown in Figs. 1 to 5, incllrsive, the brake beams are provided with integral pivot struts 29 for of the brake levers 30 therewith.

In the form of my invention shown in Figs. 10 and 11, the Side plates 1 are pro vided with guide slots 31 located between the center of each beam and the journal box, which slots receive the ends 32 of the inside brake beams 22. Within the scope of the invention either the slotted supporting brackets or the slotted side plates shown in Figs. 10 and 1'1 may be employed to support the beams, as judgment or occasion may require.

It will be,"'seen that the structures disclosed the connection further p rmit ready access to all the parts of the brake gearing for their convenient removal, repairs and replacement, and pro vide a truck frame of strength and durability to sustain the strains imposed thereon.

I claim A wheel trupk including side plates, each having a diamond-shape body portion and their outer surfaces extending between the journal boxes and slots and in axial alinement with the latter, axles journaled in the bearing boxes, wheels carried by said axles and arranged to lie inwardly of the slotted ends of the side pieces, brake beams provided with integral brake shoes to engage the tread surfaces of the wheels and having extensions beyond said shoes slidably fitted in the slots of the side pieces, said beams having extensions l'n'ojecting through the slots in the'side pieces and provided with angular enlargements slidably engaging said slots and spaced from said extensions, the latter being of greater depth than the slots to serve as stops engaging the inner surfaces of the side pieces to hold the brake beams from longitudinal movement, and said lugs being arranged 1 0 project inwnirciljv and "0 lie in rear of ihe faces of the brake hencs and in 4w |\':nar.:e of the rear surfaces ilhOlQOf, and

adapted to abut against the inner walls pf the slots when the brake shoes are worn to :1 })IQLiUiQI'HHIILLi extent; and fzistenlngs passing through the ends of the triangular extensions and crossing the siots. In testimony whereof I al'iix my eignamu'e in presence of two witnesses.
